Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.

1 to 4b are front and rear perspective view plan views and cross-sectional views of the retaining wall construction block according to the present invention. The block of the present invention includes a front surface 10 and a rear surface 20 contacting the reinforcement soil; Left and right sides 30 and 30 'having corresponding concave-convex coupling portions 32 and 32' respectively formed for concave-convex coupling between adjacent blocks; An upper surface 40 having a reinforcing member or a reinforcing member insertion groove 44 into which an anchor for connecting the reinforcing member is fitted in a front and rear direction; And a lower surface 50 corresponding to the upper surface 40, and a connection pin insertion hole h for fastening the connection pins P between upper and lower blocks on the left and right sides of the upper and lower surfaces 40 and 50. In the retaining wall construction block penetrating up and down, the earth filling part 60 penetrates from the upper surface 40 to the lower surface 50 inside the block, and blocks 10 on both sides of the front surface 10 of the block. Retreat surfaces 12 and 12 'are formed laterally and rearward so that the soil filling part 60 is exposed to the front when the upper and lower cross-shafts are formed.

In the present invention, the soil filling portion 60 of the block is composed of the front surface 61 inclined toward the front upper portion and the two side surfaces 62 and 62 'and the vertical surface 63, and the left side of the soil filling portion 60. Through-holes 64 and 64 'are formed on the right side to reduce the weight of the blocks, and the connecting pin insertion holes h are generally centered around the front and rear widths of the blocks to facilitate coupling between blocks that are staggered up and down. It is located in the part and consists of a long hole shape having a long radius toward the left and right direction of the block.

In addition, the left and right sides of the earth filling part 60 are formed with external force absorbing grooves 61a and 63a having a substantially right triangular shape in plan view, and the external force absorbing grooves 61a and 63a are shown in FIG. After the block of the invention is built up and down alternately to prevent the concentration of the shear force applied to the upper block in the middle portion of the block intersecting the block when the retaining wall is floating settled ground of the ground.

In addition, the upper surface of the vertical rib 66 formed between the soil filling unit 60 and the through-holes (64, 64 ') is formed with an anchor insertion groove (44') in the left and right direction when anchoring the block 90 When the block is constructed on the upper part in the state of inserting in advance), the anchor 90 is sandwiched between the blocks and exposed to the rear of the block so that the reinforcing material can be fastened.

In addition, the upper portion of the center of the rear wall 20 of the retaining wall is not shown in the drawing, but a lever insertion groove is formed, and if necessary, when the lever is inserted therein, the upper block is lifted and the anchor is inserted in an arbitrary position or already inserted. The anchors can be removed.

On both sides of the rear surface 20 of the block, the receding surfaces 22 and 22 'are formed in the front side so that the soil filling part 60 communicates with the reinforcement soil behind the block, which is the front and rear surfaces 22 and 22'. It has a shape symmetrical with the receding surface (12, 12 ') of (10), and when viewed from the top of the block of the present invention forms a typical boat (Boat) form that narrows the bow and stern.

In addition, the front surface 10 of the block is preferably split (split) cut to have a natural stone pattern so that the completed retaining wall after construction to reduce the bleak feeling like a concrete retaining wall.

Hereinafter, a process of constructing the retaining wall using the block having the above-described configuration will be described.

5 is a perspective view showing an example of a state in which the block of the present invention is unitized, the block of the present invention is integrated with the connecting pin (P) by vertically overlapping two or three or more blocks as shown in the figure It is transported in a unitized block (U) to be, and even when the retaining wall is constructed, it may be constructed by lifting it at a time using equipment such as a crane, and the construction process according to an embodiment of the present invention is illustrated in FIGS. 6 to 11. It is shown in detail.

6 to 11, the retaining wall construction process of the present invention comprises the steps of firstly stacking at least two or more unit blocks vertically and uniting them with connecting pins (P); Second, the first construction step of lifting the unitized block (U) at once to build on the concrete foundation (C); Third, the reinforcement soil 70 is installed on the rear of the primary unitized block U, and the reinforcement 80 is connected to the primary structured block U, and the reinforcement soil 70 is laid on the reinforcement soil 70. Compacting 70; Fourth, filling the soil in the soil filling unit 60 of the primary building block (U) and planting vegetation (seed or transplant of seeds); Fifth, the step of stacking at least two or more unit blocks vertically and unitized by the connecting pin (P); Sixth, a second construction step of constructing the second unit united block (U) to the left, right to intersect on the primary united block (U); Seventh, the reinforcement soil 70 is installed on the rear of the secondary structured block U, and the reinforcement body 80 is connected to the secondary structured block U to lay on the reinforcement soil 70 and reinforcement soil 70 Compacting); Eighth, filling the soil in the soil filling unit 60 of the block (U) secondly constructed and planting vegetation; including, the process after the second construction is the secondary construction according to the construction height of the retaining wall The same process can be repeated from the step.

The anchor 90 is preferably assembled in a state in which the block is inserted into the block for each required height when uniting the unit, but may be installed between the upper and lower blocks during the construction of the retaining wall.

Meanwhile, a non-woven drain filter 100 is installed at the rear of the overlapping portion of the block between the unit blocks U which are adjacent to the left and right to prevent the backfill soil 70 from being exposed to the front of the retaining wall. Only water can be drained to the front of the retaining wall, and as shown in FIG. 11, the drain filter 100 is also extended to the inside of the earth filling part 60 inside the block U as it is. If rainwater flows into 70), only the rainwater is drained in front of the retaining wall by this drainage filter, and the loss of soil is effectively prevented.

Preferably in the construction method of the present invention so as to gradually lower the height of the unitized block (U) in the first and second construction step, for example, as shown in FIG. 5 unitized blocks, 4 for secondary construction, 3 for 3rd construction, or 5 for 1st and 2nd construction, 4 for 3rd and 4th construction. In addition, the shear force received when the block is built up and down alternately with respect to the load received by the retaining wall block itself by gradually reducing the height of the unitized block U in each construction step. The lower portion of the retaining wall effectively prevents the middle portion of the block from being easily broken.

In other words, since the number of unitized blocks increases toward the lower end of the retaining wall, the number of overlapping blocks increases with respect to the shear force due to the load applied to the block itself. It is possible to prevent breakage.

Moreover, the block of the present invention is formed in the block itself has a resistance to the shear force so as to prevent damage to the shear force described above, which is the soil filling portion 60 formed on the upper surface 40 of the block as described above Both sides of the left and right sides are provided with external force absorbing grooves 61a and 63a forming a generally right triangle when viewed in a plane. As shown in FIG. 12, the retaining wall is constructed after the blocks are alternately constructed up and down. When the horizontally constructed block is subjected to shearing force during the floating settlement of the ground, the block can be tilted to absorb the floating settlement, and the corner portion of the lower part of the block is connected with the earth filling part 60 of the lower block. The breakage of the edge of the block is prevented as it enters the external force absorbing grooves 61a and 63a, and the middle part of the lower block concentrates the load received from the upper part. Not because it will be prevented that the front end (cleavage) by half.

In addition, according to the construction method of the present invention, the height of the unitized block (U) is gradually lowered toward the upper portion of the retaining wall, so that the number of the soil inserts 60 exposed forwardly at the intersection between the unitized blocks is also large. Since the vegetation density can be increased, when the retaining wall is built on the inner side of the road, the retaining wall can be greened in the distance and harmonize with the surrounding natural landscape without disturbing the traffic of the vehicle up to a certain height.

In addition, when the block according to the present invention is constructed using the method of building the present invention, the earth filling part 60 formed inside the united block U as shown in FIG. 11 is long (or deeply) up and down. Since it is connected, the vigorous rooting of vegetation is possible, and the part exposed to the outside of the upper part is minimized, so that the vegetation can not be killed even during the dry season, and the soil filling part 60 Soil is also interconnected with the reinforcement soil in the rear at the bottom end of the water supply to the vegetation can be effectively made the drainage of the excess supply of rainwater.

The shape and position of the absorption grooves 61a, 63a, 64a are somewhat different.

Specifically, the difference between the anchor insertion groove 44 ′ and the connection pin insertion hole h is partially formed to overlap each other, but the connection pin insertion hole h is in the form of a light beam subsidiary, As shown in FIG. 33, the upper half of the connecting pin insertion hole h penetrated up and down of the block is formed to be wider than the front and rear widths of the anchor insertion groove 44 ', and the lower half is narrow. It is reduced in width, but forms a long hole to the left and right.

Therefore, as shown in FIG. 36, an anchor (not shown) or reinforcing member in which the connecting pin P vertically inserted into the upper block U2 is inserted into the anchor insertion groove 44 ′ of the lower block U1 during block construction. While directly supporting the 80, the upper block (U2) can be retracted with respect to the lower block (U1) to give an appropriate inclination to the retaining wall, which is a reduced portion of the connection pin insertion hole (h) of the upper block (U2) ( h2) is made possible by the lower end of the connecting pin (P) inserted in the protruding state to be in close contact with the rear of the wide expansion (h1) of the upper portion of the connecting pin insertion hole (h) formed in the lower block (U1). .

In the block according to the present embodiment, the connection pin insertion hole h has a tapered portion h3 formed of an inclined surface between the wide expansion portion h1 at the upper portion and the reduction portion h2 at the lower portion thereof, thereby connecting the connection pin P. It is easy to insert and preventing the falling down of the connecting pin (P). Since the flow is small in the front and rear directions between the upper and lower blocks, the rolling and the fall are prevented in the forward direction, and the fluidity is large in the left and right directions, thereby increasing the resistance to inequality.

In addition, in the present embodiment, the external force absorption grooves 61a and 63a on both sides are extended to connect with each other, and penetrate from the front of the left and right edges of the upper surface of the block, that is, from the upper ends of the two receding surfaces 12 and 12 '. A triangular external force absorbing groove 64a is further formed to reach the rear end of the balls 64 and 64.

The block according to the present embodiment is a portion in which the load is transmitted downward by substantially contacting the upper and lower blocks when the upper and lower blocks are stacked when the straight retaining wall is constructed by the external force absorbing grooves 61a, 63a and 64a. As shown in FIG. 35, the vertical ribs 66 are formed on both sides of the middle portion of the block, and the remaining portions are substantially spaced apart from the middle portion of the upper surface of the block by the external force absorbing grooves 61a, 63a, and 64a. Will be.

The reason for the expansion of the external force absorbing grooves 61a and 63a and the external force absorbing groove 64a in the corner portion of the block according to the present embodiment is to enhance resistance to floating settlement after construction of the curved retaining wall. A detailed description thereof will be provided later.

37 is a perspective view showing another connection state of the band-shaped fiber reinforcement, the band-shaped fiber reinforcement 80 may be inserted into the band-shaped fiber reinforcement individually in both the anchor insertion groove 44 'formed on the left and right sides of the block, construction Depending on the situation of the site, the belt-shaped fiber reinforcement 80 may be connected to the left and right anchor insertion groove 44 'as shown in FIG.

38 is a perspective view showing the construction of the retaining wall using the geogrid reinforcement, the geogrid reinforcement 80 is a block by the leading end is fitted to the connecting pin (not shown) sandwiched between the upper and lower blocks (U2, U1). Will be supported.

On the other hand, Figure 39 is a front perspective view of the retaining wall showing the state that the vegetation is made on the completed retaining wall, using the block shown in FIG. By planting, it is possible to build a vegetation retaining wall.

FIG. 40 is a plan view of a curved retaining wall constructed by the block shown in FIG. 31. As described above, the portion of the upper and lower blocks substantially contacting each other when the upper and lower blocks are stacked is illustrated in FIG. As shown, the vertical ribs 66 are formed on both sides of the middle portion of the block, and the remaining portions are substantially spaced apart from the middle portion of the upper surface of the block by the external force absorption grooves 61a, 63a, and 64a. Although the block of the embodiment shown in Fig. 31 is constructed with a curved retaining wall as shown in Fig. 40, by the expansion of the inner force absorbing grooves 61a and 63a and the additional formation of the outer force absorbing groove 64a. Although the upper block U2, which is staggered with respect to the lower block U1 indicated by a dotted line, is not parallel to each other and forms a predetermined angle, the portion that substantially contacts the upper and lower blocks U2 and U1 is formed on both sides of the middle of the block. A vertical rib (66) portion, the remaining portion is so interference will not occur.

Accordingly, even when the ground subsidence occurs as shown in FIG. 43 in the state of being constructed with a curved retaining wall, the lower right corner of the upper block U2 is accommodated in the inner external force absorption grooves 61a and 63a of the lower block U1. The external force absorbing groove 64a formed on the right side portions of both upper surfaces of the lower block U1 is not in direct contact with the bottom surface of the upper block U2, so that a portion thereof is damaged or a shear force is applied to the middle of the lower block. By preventing concentration, the block itself absorbs this floating settlement so that it can withstand the floating settlement without breaking the block, that is, without breaking the retaining wall.

FIG. 41 is a plan view of a block showing a modification of the embodiment shown in FIG. 31, and FIG. 42 is a plan view showing a stacked state of the block shown in FIG. 41, which is the same as the block shown in FIG. However, the difference is that the reduced portion (h2) of the connecting pin insertion hole (h) is not formed parallel to the left and right width direction to form a long hole in the oblique direction, the connection pin insertion hole (h) of the present embodiment In the case of applying the shape, as shown in FIG. 42, in securing the fluidity in the front and rear directions between the blocks stacked up and down, the movable range of the connecting pins P vertically between the upper and lower blocks U1 and U2. In this case, the inclination of the retaining wall may be increased, and the fluidity in the left and right directions may not be significantly lower than that of the block shown in FIG. 31.

As described above, since the present invention uses a large block having a larger left and right width than the existing block, the present invention can greatly reduce the physical burden of the worker by constructing using equipment instead of directly constructing by manpower. When the block is built upside down by the receding surface formed on both sides of the block and the formed earth filling part, the earth filling part is exposed to the front of the retaining wall, and when vegetation is planted there, the front of the vertical retaining wall can be recorded. Therefore, it is possible to build a vegetation retaining wall by emptying the soil filling part. In addition, according to the construction method of the present invention by stacking the unitized block in which several blocks are stacked vertically staggered from side to side, the block is damaged by the shear force due to the load of the block itself that can be generated in the lower layer of the retaining wall. The shape of the block itself can be effectively absorbed by the external force absorbing groove so that the horizontal displacement of the block can be effectively absorbed during the floating settling. Therefore, the right corner and the center of the block can be prevented from being damaged by the shearing force. It can provide a retaining wall to minimize the
